Library technicians are trained individuals who hold a diploma in Library and Information Technology from a recognized community college or technical institute.

Library technicians are trained to perform the functional operations necessary to support a library, such as reference, cataloguing, collection management, descriptive cataloguing, interlibrary loans, reader assistance, bibliographic searching, audio/visual equipment operation and file maintenance.

Library technicians are trained to work under the direction of a professional librarian. Technicians perform a more difficult or skilled part of library work than a clerk performs, and may supervise clerical employees.

Library technicians have a variety of roles available to them. Often the role they play will depend on the type of library or setting they are working in. In larger library systems, there are often many library technician positions, many of which specialize in supporting one operational function such as interlibrary loans or copy cataloguing. In smaller libraries in Saskatchewan, library technicians may have more responsibilities, including both functional operations and leadership roles.
